KARL SCHILLER, OF IKOW, AUSTRIA-HUNGARY.

AUTUIVIOBILE CAR..

SPECIFICATION forming part of Letters Patent No. 691,078, dated January14, 1902.

Application filed January 27, 1900. Serial No. 3.053. (No model.)

To all whom t 71mg/ concern.'

Be it known that 1, KARL SCHILLER, a citizen of the Empire ofAustria-Hungary, residing at Zikow, near Prague, Bohemia,Austria-Hungary, have invented certain new and useful Improvements inAutomobile Cars, of which the following is a specification.

The motive force for actuating the driving mechanism ofautomotor-vehicles up to the present time has been gas or vapor orsteam. The working pistons are in direct communication with thecrank-shaft by means of crosshead and connecting-rod, and the wholearrangement is that of a small kind of gas, benzene, or petroleum motorarranged on a suitable vehicle-frame. The drawbacks resulting from suchan arrangement-the noisy vibratory motion (produced by an explosion atevery piston-stroke) and the escape of steam, gases, and vapors-are tooWell known to need demonstration or investigation.

The motor arrangement of the present automotor-vehicle is based on thefact that by the employment of small edorts considerable hydraulicpressures are obtained, and the practical application of this principle,together with au arrangement for the purpose of obtaining an even anduniform working, forms the object of the present invention.

In the accompanying drawings a driving` mechanism as mounted isschematically represented.

Figure l is a plan View, and Fig. 2 a side Fig. 3 is a side elevation ofa portion of a vehicle, illustrating the brake device.

The liquid to be employed is carried in a reservoir ct on the vehicleand is drawn from it and propelled into a receptacle c by a pump h. iThe receptacle c communicates by means of a pipe or pipes CZ with theinlet-orifice of a slide-valve e, While the exhaust or outlet orificecommunicates with a pipe q, returning to the reservoir a. The pistons ofthe Working cylinders drive the operating-shaft n by means of a deviceto be described hereinafter, which shaft by means of suitable toothedgearing drives the wheels of the vehicle. lVithout entering intodetailed description of the mechanism constituting such a vehicle-forinstance, cylinders g, steering and reversing gear, and the like-itshould be stated that the pump-piston is most conveniently actuated bymeans of pedals. By this means it is possible to force the liquid fromthe vessel c through the pipes d and cylinders g, thereby effecting thedriving of the vehicle. In order to render the working free of shock andvibration, the piston-rod connection of the driving-gear is formed oftwo sleeves 7a and h, one telescoping into the other, the latter beingrigidly connected to the piston-rod t, while the other is connected bymeans of a pin-joint with a connectingrod Z. In the hollow space formedby the two sleeves is arranged a spring o, which takes up some of thepressure from the piston. This pressure may be made effective in avariety of ways-viz., by the arrangement of a brake Wheel or disk p onthe driving-axle, by means of which the work produced by the pistons istransmitted after a longer or shorter time, by means of the spring o,inclosed between the sleeves 7L and 7c, directly onto the driving-axlen, or is stored up in the said spring. In operation when the pedals areactuated liquid will be forced into the cylinders and the hydraulicpressure generated therein will be transmitted to the piston andpiston-rods and from the latter to the springs o, which latter in turntransmit such pressure to the connecting-rods Z and thence to thedrivingaxle. The springs, as will be seen, act to cushion the initialmovement of the pistonrods, and it is only after the latter havetraveled a portion of their stroke that the pressure stored upin thesprings by the movement of the piston-rod will be transmitted to theconnecting-rods l. Thus by the introduction of the liquid into thecylinders and the exhaust of such liquid back to the reservoir a thevehicle will be impelled and all shocks due to the operation of thepiston-rod will be avoided. By means of such an arrangement it is easyto make use of the force stored up in the spring during the forward orreturn stroke ot' the piston by either releasing or applying the brakein the iirst case, while in the second case the spring, owing to theforce still stored up in it, tends to drive the piston to its initialposition, thereby forcing out the liquid from the correspondingcylinder.

The connection of the spring-controlled mechanism with the brake-wheel,on the one hand, andthe combination of these two mech- IOO anisms withthe pistons actuating hydraulically the connecting-rods form the chieffeatures of the present invention.

'What I claim as my invention, and" desire to secure by Letters Patent,is-

l. In a driving mechanism for automotor- Vehicles, the combination witha liquid-reservoir, a piston-cylinder, connections between the latterand the reservoir, a piston operating in the cylinder, the piston-rod, adrivingshaft, a connecting-rod connected at one end with thedriving-shaft, and a spring connection between the opposite end of theconnecting-rod and the piston-rod.

2. In a driving mechanism for automotor- Vehicles, the combination witha liquid-reservoir,of a piston-oylinder,connections between the latterand the reservoir, a piston operating in the cylinder, the piston-rod, adrivingshaft, a connecting-rod connected at one end with thedriving-shaft, sleeves on the connecting-rod and piston-rod andtelescoping one into the other, and a spring interposed between thesleeves, in the manner and for the purposes specified.

3. In a driving mechanism for automotorvehicles, the combination with aliquid-reservoir a, a pump b, pipes d and q, cylinder g, a pistonoperating in the cylinder, the pistonrod, the driving-shaft, aconnecting-rod connected at one end with the driving-shaft, sleeves hand le arranged as described, and a springinterposed between saidsleeves for the purposes specified.

4. In a driving mechanism for automotor- Vehicles, the combination witha liquid-reservoir,of apistoncylinder,con nections between the latterand the reservoir, a piston operating within the cylinder, thepiston-rod, a driving-shaft, a connecting-rod connected at one end withthe driving-shaft, a spring connection between the opposite end of saidconnecting-rod and the piston-rod, a road-Wheel shaft geared to thedrivin g-shaft and a brakedisk mounted on the road-wheel shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I

KARL SCHILLER.
